Process for printing water soluble film

Abstract

A process including the steps of: providing a water soluble film; providing an ink including between about 5% and about 30% by weight a solvent selected from the group consisting of diols, cyclic polyols, diglycols, triols, polyols, and mixtures thereof; and applying the ink onto the water soluble film.

1 . A process comprising the steps of:

         2 . The process according to  claim 1 , wherein said ink is applied onto said water soluble film by an ink application process selected from the group consisting of flexographic printing, gravure printing, lithographic printing, and pad printing. 
     
     
         3 . The process according to  claim 2 , wherein said ink comprises between about 35% and about 85% by weight water. 
     
     
         4 . The process according to  claim 3  wherein said ink is retained on a flexographic print cylinder for between about 0.5 seconds and about 8 seconds before being printed on said water soluble film. 
     
     
         5 . The process according to  claim 4 , wherein said water soluble film is provided as a continuous web moving at a speed between about 2 m/min and about 50 m/min. 
     
     
         6 . The process according to  claim 5 , wherein said solvent is selected from the group consisting of ethylene glycol, propylene glycol, butadiene glycol, cyclohexanedimethanol, cyclohexyl dimethanol, diethylene glycol, dipropylene glycol, glycerol, polyethylene glycol, polypropylene glycol, polybutadiene glycol, and mixtures thereof. 
     
     
         7 . The process according to  claim 6 , wherein said solvent is propylene glycol. 
     
     
         8 . The process according to  claim 7 , wherein said ink comprises between about 10% and about 25% by weight propylene glycol. 
     
     
         9 . The process according to  claim 8 , wherein said water soluble film comprises polyvinyl alcohol. 
     
     
         10 . (canceled) 
     
     
         11 . (canceled) 
     
     
         12 . The process according to  claim 3  wherein said ink is retained on a gravure print cylinder for between about 0.5 seconds and about 8 seconds before being printed on said water soluble film. 
     
     
         13 . The process according to  claim 12 , wherein said water soluble film is provided as a continuous web moving at a speed between about 2 m/min and about 50 m/min. 
     
     
         14 . The process according to  claim 13 , wherein said solvent is selected from the group consisting of ethylene glycol, propylene glycol, butadiene glycol, cyclohexanedimethanol, cyclohexyl dimethanol, diethylene glycol, dipropylene glycol, glycerol, polyethylene glycol, polypropylene glycol, polybutadiene glycol, and mixtures thereof. 
     
     
         15 . The process according to  claim 14 , wherein said solvent is propylene glycol. 
     
     
         16 . The process according to  claim 15 , wherein said ink comprises between about 10% and about 25% by weight propylene glycol. 
     
     
         17 . The process according to  claim 16 , wherein said water soluble film comprises polyvinyl alcohol. 
     
     
         18 . (canceled) 
     
     
         19 . (canceled) 
     
     
         20 . A process comprising the steps of:
 providing a water soluble film comprising polyvinyl alcohol;   providing an ink comprising between about 10% and about 25% by weight propylene glycol;   applying said ink onto said water soluble film; and   incorporating a surface treatment composition onto, into, at least partially enclosed by, or enclosed by said water soluble film;   wherein said surface treatment composition is selected from the group consisting of a fabric conditioner, a laundry conditioner, a fabric detergent, a laundry detergent, a laundry rinse additive, a hard surface cleaner, a hard surface treatment composition, an air care composition, a car care composition, a dishwashing composition, a composting composition,   a cleaning product, and combinations thereof;   wherein said ink is applied onto said water soluble film by an ink application process selected from the group consisting of flexographic printing, gravure printing, lithographic printing, and pad printing; and   wherein said water soluble film is provided as a continuous web moving at a speed between about 2 m/min and about 50 m/min.
